From most regional species, O. shorti can be distinguished from most species of the genus except O. fikaceki and O. dinghu by its small to medium size, its rounded posterolateral margin of the pronotum, lack of procoxal spines, with sparse and long setae on abdominal ventrites 1–4, lack of distinct elytral systematic punctures, and the metafemora without microreticulation. It is extremely close to O. fikaceki Short & Jia and O. dinghu Short & Jia. It can be separated from both species by the aedeagus (Fig. 4) with the outer margin of parameres distinctly curved inwards and clearly narrowed apically; the median lobe abruptly narrowed at apical one-fourth; and with the gonopore situated one and half times of its length below it. Description. Size and Form. Total body length= 3.6 –4.0 mm. Oval, strongly convex. Elytra slightly longer than wide. Color. Dorsum black; head, pronotum and often elytra with a subtle green iridescent sheen. Maxillary and labial palps yellow, with apex of maxillary palpomere slightly darkened. Legs, epipleura, lateral margins of prosternum and posterior half of each ventrite yellowish brown, with remainder of venter slightly to moderately darker reddish brown. Head. Ground punctation on labrum, clypeus and frons slightly variable in size from almost undetectable to fine; fairly densely distributed, distance between punctures 0.5–1.5 x the width of one puncture. Systematic row of punctures on the labrum very dense, more or less forming a lateral, shallow median groove, and set with a dense row of long erect yellow setae. Frons with an irregular row of systematic punctures mesad of each eye, bearing a few fine setae. Clypeus with a few nearly undetectable systematic punctures along anterolateral margins, slightly larger than surrounding punctation and usually bearing short setae. Maxillary palps very short, subequal in length as width of labrum; segment 2 slightly bulbous, apical segment slightly longer than penultimate. Labial palps three-fourths as long as width of mentum. Mentum quadrate, anterior margin slightly convex; anterior half portion bearing very fine and scattered punctures, including two small clusters of punctures mediolaterally that bear fine setae; posterior half portion almost glabrous, sometimes with a few nearly undetectable punctures. Thorax. Ground punctation on pronotum and elytra very irregular in size, composed of both extremely fine and moderately coarse punctures, which are generally mixed and evenly distributed. Pronotal systematic punctures present, but blending with larger general punctures, usually not more than 1.5 x the size of general punctation and set with a fine recumbent seta. Lateral margins of pronotum appearing without setiferous punctures. Posterolateral corners of pronotum evenly rounded. Sutural punctation on elytra absent or unmodified from general punctation. Elytra without distinct rows of larger punctures, as they blend uniformly with the largest of the ground punctures; these rows (of systematic punctures) can be detected by the presence of a fine, short seta. Prosternum with median carina along entire length, with a small blunt tooth anteriorly; without long spines or hairs anteriorly. Mesosternal process with lateral extensions sloping evenly downward; apex set with a few long fine setae. Metasternum with small oval glabrous area posteromedially, slightly longer than wide, length of glabrous area about two-fifths the total length of the metasternum. Pro- and mesocoxae densely pubescent; without spines. Protibiae with 6–7 spines on dorsal face. Protarsal segments 1–4 small, subequal in length, apical segment slightly shorter than segments 1–4 combined. Metafemora without microreticulation. Abdomen. Ventrites 1–4 with two lateral rows of very long, fine setae; longest setae longer than the setae around the metasternal glabrous area. Fifth ventrite entire, with dense, uniform setae over entire surface. Aedeagus (Fig. 4) with outer margin of parameres distinctly curved inwards and clearly narrowed apically, not expanded on inner face apically; median lobe abruptly narrowed at apical one-fourth, appearing bilobed at apex, with gonopore situated one and half times its length below it. Etymology. Named in honor of Dr. Andrew Edward Z. Short, Division of Entomology, Biodiversity Institute and Department of Ecology & Evolutionary Biology, University of Kansas, and avid hydrophilid specialist who has collaborated with first author. Distribution. China (Guangdong & Hong Kong). Biology. Living on wet rock face (Fig. 5), sometimes living with Cymbiodyta orientalis Jia & Short together.Published as part of Jia, Fenglong & Maté, Jason F., 2012, A New Species of Oocyclus Sharp From Southeastern China (Coleoptera: Hydrophilidae), pp. 81-84 in Zootaxa 3509 on pages 81-83, DOI: 10.5281/zenodo.28250

BODY (Fig. 3A): Length (TL) 1.15mm (HT), range 1.04–1.27mm (average 1.14mm, n=6). Body ovoid, regularly convex, colour reddish brown, densely pubescent with long and semidecumbent light yellow hairs. HEAD: Eyes large (EyL= 80 µm [HT], range 73-82 µm, n=4), widely separated (IoD= 217 µm [HT], range 215- 228 µm, n=4), notched posteriorly. Head thinly margined, with only a few shallow, setigerous punctures on the vertex and around the disc of the frons. Antennae long (AnL= 470µm, [HT]), segments 3-7 parallel-sided and elongate, 8 th basally ovoid; 9-10 clubbed, 9 th angulately moniliform basally, 10 th regularly moniliform basally and 11 th oval. THORAX: Pronotum wide (PW= 0.50 mm [HT], range 0.46–0.53mm, n=6), unicolorous, transverse (1.60–1.73 PW:PL) widest behind middle, regularly convex, lateral margins explanate and slightly elevated, edges strongly serrated and ciliated with backwardly arranged hairs, edge evenly curved til basal quarter, then angled medially to basal corners, base sinuate and narrowly impressed throughout, hind corners lateral edge straight, neither sinuate nor projected. Pronotal surface shiny, microsculture absent, without any trace of medial impression or fovea, narrowed basally, puncturation clearly impressed, punctures 4–5µm wide and spaced 3–5x their diameter, regularly distributed, setigerous, each with a long, semidecumbent hair. Elytra wide (EW= 0.60mm [HT], range 0.60–0.72mm, n=6), convex, oval, base bordered, humerus not denticulate although the serrated elytral edge may give the appearance of a denticle. Surface shiny, microsculpture absent, strongly punctured throughout, punctures setigerous, with semidecumbent yellow hairs densely arranged and of similar length on elytral disc and sides (length [HT] 50–70µm), puncturation densest at base and disc, becoming gradually sparser towards the apex and sides. Lateral edge of elytra expanded from humerus and gradually becoming narrower towards apex, serrated in basal quarter. Scutellum triangular, with a few shallow setigerous punctures. Alae of usual Sindosium type. Proventrum (Fig. 3A) narrowed longitudinally in front of procoxae, with a single c-shaped fovea on the anterolateral corner of each coxa, as long as the coxal length and deeply impressed. Combined coxal width half that of the anterior prothoracic aperture. Anterior and posterior margins of the proventrite with a row of elongate foveae, anterior row well impressed, posterior one mostly efaced. Mesoventrum, with well impressed collar which does not clearly slope backwards but ends sharply on to the lateral margins. Latter without distinct humeri, collar with posterior projection elongate and apically rounded. Disc of mesoventrum with a non-carinate projection (keel) that rises abruptly and almost touches the much smaller posterior projection of the collar, posteriorly with a pair of deep and densely pubescent depressions. Mesocoxae close, separated by 1/6–1/8 of their width. Metaventrum with scattered, long pubescence, dense laterally and absent on disc, anterior edge raised and slightly projected between mesocoxa, posterior edge with falcate, bifid projection (Fig. 4B) between metacoxae. Metaepisternal posterior suture (Fig. 3B) less divergent from anterior one, partially subparallel. ABDOMEN (Fig. 4C): Each ventrite with a basal row of very fine setae on disc, each seta emerging from a small, fine pore. Setation similar in strength and density on all abdominal segments. Aedaegus (Fig. 4E) typical of Sindosium with well developed parameres, strongly narrowed in the middle and sporting a pair of pores, apices parallel, at apex with three unequal setae, the apical one longest and facing forward, and the two shorter setae set clearly apart from the apical one, aproximate and pointing medially. Median lobe narrower than previous species, with apex converging to a sinuate point, the endophallic pore situated in the apical 4 th and with a very simplified and reduced internal structure that is level with paramere apices. Spermatheca (Fig. 4D) bulbous, almost symmetrical, with neck wider than base, regularly converging and aligned with neck. Etymology: named after Lamington National Park (Queensland, Australia), locality where the majority of the specimens of this new species have been collected. Diagnosis: see comparative diagnosis under S. queenslandicum n.sp. Distribution: restricted to South-East Queensland with one isolated record from MEQ. The paucity of records in such a well collected area suggests that the species is either rare or has highly restricted habitat needs which are limited to the higher reaches of mountains peaks in SEQ such as the Scenic Rim and the Bunya Mountains (Fig. 5, see discussion). Similar habitats occur in the New South Wales North Coast (NSWNC), so additional populations are expected in this area.Published as part of Maté Nankervis, Jason F., 2020, Description of two new species of Sindosium Johnson, 2007 from Australia (Coleoptera, Ptiliidae), pp. 528-540 in Zootaxa 4895 (4) on pages 533-537, DOI: 10.11646/zootaxa.4895.4.4, http://zenodo.org/record/435885

Description. BODY (Fig. 1A): Length (TL) 1.1 mm (HT), range 1.08–1.26mm (average, 1.19 mm, n=21). Body ovoid, regularly convex, colour reddish brown, densely pubescent with long and semidecumbent light yellow hairs. HEAD: Eyes large (EyL= 60µm [HT], range 55-71µm. n=6) widely separated (IoD= 220µm [HT], range 201- 230µm, n=6), notched posteriorly. Head thinly margined, with only a few shallow, setigerous punctures on the vertex and around the disc of the frons. Antennae long (AnL= 407µm), segments 3–7 parallel-sided and elongate, 8 th elongate with sides curved; 9–10 clubbed, basally regularly moniliform; 11 th oval. THORAX: Pronotum wide (PW= 0.49mm [HT], range 0.46–0.57mm, n=21), unicolorous, transverse (1.55- 1.82, PW:PL), widest behind middle, regularly convex, lateral margins explanate and slightly elevated, edges serrated and ciliated with backwardly arranged hairs, base sinuate and narrowly impressed throughout, hind corners laterally sinuate and projected outwards slightly. Pronotal surface shiny, microsculpture absent, without any trace of medial impression or fovea, narrowed basally, puncturation deeply impressed, punctures 5–6µm wide and spaced 2–3x their diameter, regularly distributed, setigerous, each puncture with a long, semidecumbent hair. Elytra wide (EW= 0.57mm [HT], range 0.54-0.62mm, n=21), convex, oval, base bordered, humerus not denticulate although the serrated elytral edge may give the appearance of a denticle. Surface shiny, microsculpture absent, strongly punctured throughout, punctures setigerous, with semidecumbent yellow hairs clearly longer (40–50µm, [HT]) and denser on sides than on disc, puncturation densest at base and disc, becoming gradually sparser towards the apex and sides. Lateral edge of elytra expanded from humerus and gradually becoming narrower towards apex, serrated in basal quarter. Scutellum triangular, with a few shallow setigerous punctures. Alae of usual Sindosium type (Fig. 2F). Proventrum (Fig. 2A) narrowed longitudinally in front of procoxae, with single deep, c-shaped fovea on either side of each coxa, almost as long as the coxal length and strongly impressed throughout. Combined coxal width 3/5 the width of the anterior prothoracic aperture. Anterior and posterior margins of the proventrite with a row of distinctly impressed, elongate foveae. Mesoventrum, with strongly impressed collar which does not clearly slope backwards but ends sharply on to the lateral margins. Latter without distinct humeri, collar with a posterior, triangular projection. Disc of mesoventrum with a non-carinate projection (keel) that rises abruptly and almost touches the much smaller posterior projection of the collar, latter with a pair of deep and densely pubescent depressions posteriorly. Mesocoxae close, separated by 1/4–1/5 of their width, Metaventrum with scattered, long pubescence, dense laterally and absent on disc, anterior edge raised and projected between mesocoxae, posterior edge with sinuate, regularly acuminate bifid projection between metacoxae (Fig. 2B). Metaepisternal posterior suture widely divergent from anterior suture, never subparallel or convergent (Fig. 1B). ABDOMEN (Fig. 2C): Each ventrite with a basal row of setae on disc, each seta emerging from a strong pore that is granular on ventrites 4–5. Row of setae on 5 th ventrite much denser than on the other abdominal segments. Aedaegus (Fig. 2E) typical of Sindosium, with well developed parameres, quite narrowed in the middle and sporting a pair of pores, their apices slightly spatulate, at apex with three elongate and isometric setae, apical seta pointing forward, proximal setae closely set, pointing medially. Median lobe wider than in S. lamingtoni n.sp., with apex regularly acuminate, the endophallic pore situated almost midway along its length and with a larger and more developed internal structure that is M-shaped and located well below the paramere apices. Spermatheca (Fig. 2D) bulbous, non-symmetrical, with neck narrower than base, the latter obviously bent and completely not aligned with neck. Etymology: named after the Australian state of Queensland, to which it is restricted. Diagnosis: morphologically it is closest to S. lamingtoni n.sp., from which it can be distinguished by the shape of the 8 th antennal segment (parallel in S. queenslandicum n.sp. and basally ovoid in S. lamingtoni n.sp.), the shape of the hind corners of the thorax, width and relative shape of the of the metaepisternum (Fig. 2A & Fig. 4A), shape of the bifid tooth between the metacoxae (Fig. 2B & Fig. 4B) and genitalia. Both species closely resemble S. foveatum Johnson, 2007 and S. collinsi Darby, 2019. From the former they can easily be distinguished by the lack of impressions on the thorax and the shape of the aedaegi. From the latter by the much longer pubescence, the structure of the mesoventrum (collar more acutely developed, sulci on either side of projection smaller) and narrower separation of the mesocoxae. Distribution: restricted to areas within Mid-East and North-East Queensland, probably limited to vine thickets or rainforest patches (Fig. 5).Published as part of Maté Nankervis, Jason F., 2020, Description of two new species of Sindosium Johnson, 2007 from Australia (Coleoptera, Ptiliidae), pp. 528-540 in Zootaxa 4895 (4) on pages 529-533, DOI: 10.11646/zootaxa.4895.4.4, http://zenodo.org/record/435885
Towards a revision of the Palaearctic species of Aphodius Hellwig, 1798, subgenus Liothorax Motschulsky, 1860 (Coleoptera, Scarabaeidae, Aphodiinae)
No full textThe Palaearctic species of Aphodius Hellwig, 1798, subgenus Liothorax Motschulsky, 1860 are revised using a combination of chromosome analysis, molecular phylogenetics and morphological statistical analysis. Sixteen species are recognised, one of which is shown to comprise two subspecies. Based mainly on the morphology of the aedeagal endophallus and the phylogenetic analysis, they are placed in two groups: the. niger group, apparently monophyletic, comprising Aphodius (Liothorax) niger Illiger, 1798, A. (L.) muscorum (Ádám, 1994), stat. rest., A. (L.) felix sp. nov., A. (L.) bellumgerens sp. nov., A. (L.) bameuli sp. nov., A. (L.) krelli sp. nov., A. (L.) isikdagensis (Balthasar, 1953), A. (L.) alberti sp. nov. and A. (L.) wilsonae Maté et Angus, 2005, stat. rest.; and the plagiatus group, almost certainly paraphyletic, comprising A. (L.) plagiatus (Linnaeus, 1767), including A. (L.) p. plagiatus and A. (L.) p. sinoplagiatus subsp. nov., A. (L.) rodrigoi sp. nov., A. (L.) discoides A. Schmidt, 1916, stat. rest., A. (L.) rutilipennis (Baudi di Selve, 1870), stat. rest., A. (L.) chellala sp. nov., A. (L.) kraatzi Harold, 1868, and A. (L.) rusakovi Gusakov, 2004. A key to the species is given as well as details of their morphology, distributions, and habitats
